Definitions

  • the sealing of plastic bags filled with a particular product, for example bread is commonly achieved by folding a length of pressure sensitive adhesive tape around the gathered together neck of the bag.
  • the adhesive tape is folded such that the ends of the tape stick to each other to form a closed loop around the neck of the bag.
  • One way to achieve a resealable tie is to provide paper tabs covering the adhesive at the end portions of each tie.
  • the adhesive tape is provided from a roll of tape and is cut into predetermined lengths for each tie just prior the to application of the tie to the neck of a bag.
  • the tape is unwound from the roll and paper tabs are applied to the tape at predetermined intervals.
  • the paper is also unwound from a roll and cut into tabs on contacting the adhesive tape.
  • the tape with paper tabs attached is then cut through the supplied paper tabs so that each end of each length of tape to form each tie includes a paper tab.
  • a bag tying machine of this type is disclosed in GB-A-1381871. This type of bag tie has proved extremely successful but requires complex and reliable machinery capable of handling sticky pressure sensitive adhesive tape to prepare and apply the bag ties.
  • a bag tying machine includes:
  • the present invention provides a bag tying machine which produces adhesive tape ties with non-adhesive end portions which does not require complex machinery to form the tie close to the sealing means. It is also less costly than other currently available methods.
  • the cutting means cuts the tape in the centre of the non-adhesive portions of the tape.
  • the detector is an optical detector capable of detecting differences in reflection from the adhesive and non-adhesive portions. The detector may detect differences in colour.
  • a wide roll of adhesive tape 1 is unwound and the tape passes under a flexo printer 2 which prints a band of coloured ink 3 across the entire width of the tape.
  • the bands of coloured ink are all of equal width, approximately 25mm.
  • the interval between successive bands of ink is approximately 65mm.
  • the coloured ink is of a different colour to the adhesive side of the tape and where the ink is applied it neutralises the adhesive on the tape i.e. the adhesive on the tape is made non-adhesive by the application of the ink onto it.
  • Suitable inks include Flexo vinyl masking (yellow/red/green/blue) CON 043 available from Inktech of Crawford Street, Rochdale, OL16 5NU, UK.
  • the adhesive tape is applied to the neck of a filled bag with movement of the gathered together neck of the bag through a bag tying machine.
  • a typical bag tying machine is shown in GB-A-1381871 and only the differences from such a conventional machine are shown in Figure 2 and described subsequently.
  • the neck of the bag 10 contacts the adhesive side of a length of adhesive tape 1 arranged perpendicular to the direction of motion of the neck of the bag.
  • the neck continues on its path pulling the tape with it and passes through a pair of rollers 11.
  • the action of the rollers folds the length of adhesive tape around the neck of the bag and onto itself to form a seal.
  • the sealed bag then moves on out of the tying machine.
  • Figure 3a shows a pair of gripper arms 12 in an open position at a point in the tying cycle just after a seal has been formed around one bag, cut by a pair of cutting blades 13, released by the gripper arms and moved out of the tying machine.
  • the gripper arms 12 are moved up and down and opened and closed by pneumatic piston and cylinder assemblies as described in GB-A-1381671.
  • the gripper arms 12 have a pneumatic brake system which consists of a slide bar 15, which moves up and down with the gripper arms 12, and brake pads 16 which are anchored in a fixed position on the tying machine.
  • the brake pads 16 are shown in a released position as the gripper arms 12 are about to move up and grip the free end of the tape 1 in the next step.
  • Figure 3b shows the gripper arms 12 at their uppermost point, where the gripper arms 12 close so gripping the free end of the tape 1.
  • the tape 1 is then pulled as the gripper arms 12 move down, as shown in Figure 3c, until a detector 14 detects the leading edge 18 of a printed band of tape.
  • a proximity switch 17 detects the tail 19 of the brake slide bar 15, and when both detections are made, as shown in Figure 3d, the brake pads 16 are applied to brake the movement of the brake bar 15 and hence halt the movement of the gripper arms 12.
  • the detector 14 is an optical detector which sends a beam through an optic fibre to the tape and detects the reflected light re-entering the optic fibre. From a change in the reflected light the boundary between inked and non-inked sections of the tape can be ascertained.
  • a suitable detector is manufactured by Keyence Corporation of Milton Keynes, UK and designated their CZ-41.
  • Figure 4 shows a length of inked adhesive tape 1 prior to it being cut into lengths.
  • the length of each inked band 3 is 25mm.
  • the inked bands are eventually cut in the middle, leaving inked, non-adhesive tabs 3 of 12.5mm in length.
  • This is sufficient length for a consumer to grip with finger and thumb in order to peel apart the seal.
  • the interval between inked bands must be of sufficient length to encompass the neck of the gathered bag to be sealed, in this example it is 65mm. This means that the total length of one tape seal is 90mm. For some applications the total length of each seal is 110 mm.
  • Figure 5 shows the neck of a bag with an adhesive tape seal applied.
  • the inked tabs 3 are free and form gripping portions.
